I have VUE 7 .20-04 .
   I use Windows XP with 4 GB of memory installed on a Dell inspiron 531. The image renders fine in Preview, but I still get a black square when I try to render it to disk. In the render options, I checked Final, internal renderer,render to disk, under those options, I gave it a title and set it to save to "My Pictures" folder, I then skipped over to picture size and resolution, where I set it for Academy standard Flat [37:20], 900 X486 and a DPI setting of 300. 
   These are the same settings I used in VUE 6 Espirit and they worked fine.  I'm forgetting to set something- but I don't know what.
